"It just broke my heart," she said. "I didn't want to take off the costume."

Disney officials told Spielman they didn't want kids to think she was the official Tinkerbell and gave her a free T-shirt to change into before allowing her into the park.

Disney's website warns that "adult costumes or clothing that can be viewed as representative of an actual Disney character" may lead to a "refusal of admittance," although the theme park does offer pirate and princess makeovers to younger children.

"They were talking how the little girls, it ruins their dreams," Spielman said. "But it ruined my dreams because I just want to be Tinkerbell."

Disney reportedly gave Spielman's family Fastpass tickets so they could bypass lines on rides while she changed clothes.
